Hello
I'm working on sonic unleashed.
I'm near the solution but I'm not enough skilled to finish
The game is compressed and packed
xmemcomp (xbox) for compress and arsys (segs archive) for pack.
for decompress:
https://aluigi.altervista.org/bms/xcompress_file.bms
unpack :
https://aluigi.altervista.org/bms/arcsys.bms
there is no problem for xcompress side bms2xtl works perfectly and give me a database.
so the first step is ok, but I don't know how use the second step (arcsys)
